Product Overview

Stainless-Steel Material Shackle for Key Rings / Swivel Snap Hook for Keys – Model ZB1804-KS Series
RICHWITS turns the proven 30° rail base into a pocket-size, salt-proof swivel shackle for keys, EDC tools and mini-dive accessories.
Precision-investment-cast from 316 marine stainless, then mirror-polished and passivated for lifetime immunity to sweat, salt-spray and tropical humidity.
30° swept neck eliminates sharp protrusion; 22.8 mm or 25.8 mm ring diameter slips over thumb for one-hand operation.
Five micro sizes (22–25 mm bore) cover working-load limits from 80 kgf to 150 kgf—perfect for key rings, USB sticks, dog tags or small-boat fender lines.
